Where appropriate, the documentation must show general layout, reduced levels, Equipment position, coordinates or offsets, speed zones, conduit and pit locations, mounting structure positionsand any protective barriers. If appropriate, details of Equipment brackets and support connections must also be provided. Any drawings provided pursuant to this clause must be prepared in accordance with the Principal’s drafting standards and guidelines, available from:
If not submitted beforehand, the documentation required by this Clause must be submitted at least 28days prior to the commencement of site work.
Provision of this documentation shall constitute aHOLD POINT.
3.ELECTRICAL AND TELECOMMUNICATIONS REQUIREMENTS
3.1General
All installations must be in accordance with PartR62 “Mains Power”and AS 3000.
Work on any part of the system must only be carried out by a person who is suitably qualified and licensed.Prior to the commencement of this work, the Contractor must provide evidence of the appropriate licence(s).
Provision of this evidenceshall constitute aHOLD POINT.
3.2Cables, Conduits and Pits
Conduits and Pits must comply with PartR53 "Installation of Conduits and Pits". Electrical cables must comply with AS 3008and telecommunications cables must comply with PartR70 “Telecommunications Cabling”.
Unless specified otherwise, the Contractor must install all conduits, pits and cables necessary for the provision of communications and power to the Equipment. The location of conduits and pits shown on Drawings may be approximate only. Prior to installation, the Contractor clearly mark the proposed position of conduits and pits(including sizes and types) on the surface.Following the marking out and prior to the commencement of excavation, a HOLD POINTmust apply.
A pit must be installed adjacent to each item of Equipment. Outstations must have separate power and communications pits. Single devices may share a common power and communications pit providing segregation requirements are met.
Subject to obtaining prior written approval, the Contractor may install conduits directly between adjacent Equipment sites if the Equipment sites are separated by less than the distance from the equipment to the backbone; for example, a CCTV camera located adjacent to an outstation.
All cables must be continuous and without joints except at termination points or where the cable size is required to be reduced. Joints must be accessible and not located within conduits. The Contractor must:
(a)check conduits for damage and presence of foreign material;
(b)clean the conduits as required before drawing cables through them;
(c)not place excessive strain on any individual core, individual cable or cables during the drawing in process;
(d)replace any cable damaged during installation;
(e)label all cables and terminations with permanent markings, which must not be hand written; and
(f)maintain adequate segregation between LV, ELV and data cables.
(g)Leave adequate spare cable in loops in pits, to enable cost efficient and timely repair in the event that the cable is damaged or severed.
The Contractor must supply and install a submersible line fuse holder in anelectrical service pit located between the service point and the outstation/distribution board. The electrical service pit must be located as near as practicable to the service point.
The Contractor must provide an earth stake in a pit adjacent to each Outstation and distribution board. The earth stakemust protrude into the service pit by a minimum of 150mm. Where specified, earth stakes in pits must also be provided adjacent to other Equipment. Copper clad, copper plated earth stakes or solid copper strips must be used as a minimum.
3.3Fusing
Where Equipment is powered sequentially, each Outstation/switchboard must:
(a)be protected by a fuse/circuit breaker; and
(b)contain a sub main fuse/circuit breaker. Where possible, these fuses/circuit breakers must be ‘cascaded’ in rating such that a fault in a submain will only result in the fusing/tripping of the sub main fuse/circuit breaker.
The design of the power reticulation to each device must include a method of protection and/or isolation so that;
(a)in the event of a device being damaged or suffering an internal or cabling fault which activates (ie blows) a supply fuse, that the fuse blown only removes power to that device, and not others; and.
(b)In the event that a device needs to be isolated, the supply for that device can be easily and safely isolated at the device, and also at the pit from which the device is powered
Acceptable methods of achieving the above are the installation of a fuse/circuit breaker at the device, and also installation of an inline submersible fuse installed in the pit from which the power supply for that device is derived.
3.4Wireless Communications
If wireless technology has been specified to avoid the need for conduits and pits, the wireless communications and communications Equipmentmust comply with the applicable Australian and ACMA Standards.
Wireless communications to devicesmust be from the closest TMSO. Communications interface Equipment and antennae must be installed at the TMSO to facilitate communications between the TMSO processor and the device. Wireless communications must not be affected by normal maintenance activities. Antennas must not be co-located on see saw poles with other equipment.
Corresponding communications interface Equipmentmust be installed at the devicesite. This Equipmentmust be suitably interfaced to the devicecontroller.
4.INTEGRATION
This Clause only applies where STREAMS compatibility[D1] is specified.
4.1STREAMS Compatibility
The Contractor must provide evidence of STREAMS compatibility, which may include having satisfactorily passed STREAMS acceptance testing (SAT). If the Contractor proposes to use Equipment not already defined as STREAMS compatible, the Contractor must arrange for STREAMS compatibility to be proven.
Evidence of STREAMS compatibility shall constitute aHOLD POINT.
4.2General
Each item of Equipment and/or associated system must allow automatic operation via STREAMS and local manual operation independent of STREAMS. Unless otherwise specified, communication with STREAMS must be by one of the following means (in the following order of preference):
(a)Direct Ethernet or serial connection to a Field Processor (FP);
(b)Remote Ethernet or serial (for example, using a serial/fibre media converter) connection to an FP located elsewhere and / or workstation on the Principal’s Telecommunications Network.; or
(c)connection to the Principal’s TMC.
4.3Messaging Requirements
Equipment that primarily provides data to STREAMS, for example vehicle detectors, must provide event-driven messages to minimise or avoid polling between the Equipment and Field Processor/ STREAMS. Equipment that requires frequent polling must communicate at a sufficient data rate for all the available data to be exchanged within a 2 second interval.
Event-driven messages must contain a time stamp marking the time the event occurred. Where communications from Equipment are mostly event-driven, a heartbeat (or status) message must be emitted by the Equipment at least every minute.
5.INSTALLATION REQUIREMENTS
5.1General
Prior to installation, the Contractor must ensure that all records demonstrating compliance with PartR60 “Supply of ITS Equipment” and other relevant Parts for the supply of the Equipment have been provided.
Provision of this documentation shall constitute aHOLD POINT.
5.2Location and Layout
The general layout and installation of the Equipment must:
(a)comply with the requirements of Clause 6 “Site Maintenance Access”;
(b)be designed and installed to provide rapid, easy and safe access for maintenance purposes; and
(c)minimise, and wherever practicable eliminate, the need for traffic control during maintenance activities.
Where the Equipment has components located on opposite sides of the carriageway, any physical connection must be immune to any future road widening envisaged in the Contract.
Unless otherwise specified, where Equipment is mounted above the carriageway, the vertical clearance from the bottom of the support structure and/or the Equipment enclosure to the road surface must be a minimum 6.0 metres.
5.3Wiring Enclosures
Each ITS device site must be provided with conduit infrastructure necessary for the complete operation of the device. Conduit infrastructure includes cable access from the backbone conduit network to the ITS field cabinet and/or field device. Cable infrastructure must be installed in accordance with PartR70 “Telecommunications Cabling”. After installation of cables, the associated conduits and/or glands must be sealed to prevent vermin entry.
Cables for pole mounted devices must connect to the device by entering the pole underground at its base, and exiting the pole either directly into the device enclosure (eg directly into a pole mounted equipment box), or exiting to the device at a height which prevents access to the conduit while standing at ground level.
5.4Equipment Enclosures
Ground mounted Equipment enclosures must be installed on a concrete plinth. The gap between the plinth and enclosure must be vermin-proof and prevent corrosion of the enclosure or its fixings. Enclosures must be installed such that when all doors are fixed in the open position, visibility of the approaching traffic flow is maximised for maintenance personnel working in the enclosure. The plinth must be large enough to allow for service personnel to walk on the plinth around the device while all doors and access areas are open.
Equipment enclosures must be positioned to minimise direct solar radiation and must not be painted a dark colour.
5.5Vehicle Barriers
Where road-side barrier treatments exist or are required adjacent to the Equipment site, the barriersmust be in accordance with AS3845. Where vehicle barriers are to be provided on a road which is trafficked at the time of installation, the barriers (or temporary barriers) must be installed prior to commencing civil works for the Equipment mounting foundations.
6.SITE MAINTENANCE ACCESS

(b)provide a minimum sight-distance of upstream carriageway (from within the vehicle) equal to the distance required to allow the vehicle to accelerate to 80% of the carriageway’s design speed.
(c)be laid out so that the maintenance van has sufficient parking space so that it does not park over any pits in the parking area
6.3Maintenance Area for Equipment Sites
An access path must be provided to each Equipment site for the movement of maintenance personnel between the carriageway access point and the Equipment. The access path and the area around the Equipment site must:
(a)be evenly graded so as not to exceed 1:3 gradient;
(b)suitable for safe, all-weather access;and
(c)be fitted with safety barriers around the site if working on or near the site would be hazardous without the barriers.
Concrete steps may be provided to optimise path alignment. Where steps are provided, these must be in accordance with the relevant standards and codes. A minimum 100mm thick, rectangular concrete pad must be provided for a minimum 1200mm width around all Equipment enclosures and/or mounting plinths at the site. The access path and the area around the Equipment site must be free of tripping and falling hazards.
